Volcano eruption – not meteor strike

A team of scientists based in the US have analysed layers of sediment in Halls Cave, Texas, which have shown to be consistent with volcanic eruptions.

Michael Waters, director of The Center for The Study of the First Americans and Distinguished Professor at Texas AM University, said: “It is an exceptional record that offers a unique opportunity for interdisciplinary cooperation to investigate a number of important research questions.

“One big question was, did an extraterrestrial impact occur near the end of the last ice age, about 13,000 years ago as the ice sheets covering Canada were melting, and cause an abrupt cooling that thrust the northern hemisphere back into the ice age for an extra 1,200 years?

“This period of rapid cooling coincides with the extinction of a number of species, including camels and horses, and the appearance of the Clovis archaeological tradition.”
